HI Stephan, I don't have any idea what might be up with the driver, it's rather counter-intuitive that doing the on screen stats would improve things.
My own suggestion would be to add a final draw callback to the viewer's Camera that calls glFlush or glFinish to see if either of these has an effect. This might provide you a bit more feel for the nature of the driver bug. Robert.
